Many people have long speculated as to whether lyrics in Prince's song Life 'O' The Party referred to Jackson, the song featuring on the 2004 album Musicology had a lyric that went: "My voice is getting higher/And I ain’t never had my nose done/That's the other guy."

When the Purple Rain singer pulled out of charity song We Are The World, it was claimed to be because he did not want to appear alongside the King of Pop.

"I called Prince and his folks and they arranged it (for Michael to come down), they have an infamous feud and I brought them together," he told the BBC.

But during the performance Michael was left pretty offended when Prince reportedly played his bass right in MJ's face.

According to Rolling Stone contributing editor Steve Knopper who took on the task of writing MJ's biography, he said that Michael wasn't happy about the incident.

He told Esquire magazine: "There was a point during the show where Prince was playing bass and he came out into the audience with this giant bass—he knew where Michael was sitting—and he walked right up to Michael and started playing bass in Michael's face. Like aggressive slap bass.

"The next morning, Will went over to Michael's house for breakfast, and they're talking about Prince and the show. And then Michael goes, 'Will, why do you think Prince was playing bass in my face?'
